Gropello Cairoli, rice fields and railway in the Lomellina
The name recalls the Cairoli family, the brothers from Pavia who fought in the Risorgimento, Italy's 19th-century unification, and who were linked to this town. Gropello Cairoli lies in the eastern Lomellina, west of Pavia, on a plain of rice paddies, irrigation channels and farmsteads, where spring transforms the landscape as the fields are flooded for rice sowing.
The centre is compact, with low houses and a few historic buildings; around it are detached houses and small blocks of flats, and in the countryside the large farmsteads (cascine), some still working, others waiting to be restored. For commuters the railway matters: published timetables show 1 stop in the municipality with 1 train line and 1 bus line, and the report measures the distance from the house to the station. Pavia is close and Milan within reach.
Istat, the national statistics office, counts 4,271 residents in 2023, down 7.0% on 2011 (321 people). The average age is 47.9, slightly above the province of Pavia, with over-65s at 26.5% and foreign residents at 8.9%. Declared incomes are just below the provincial average.
On an irrigated plain, the official flood maps need reading case by case, especially near channels and watercourses, and the report does this for each address. Gropello is in seismic zone 3, like 157 of the 184 municipalities in the province, with an expected ground acceleration of around 0.059 g. In farmsteads and old houses, the roof, rising damp and the services are what count.
